STEAM-COOKER.

SPECIFICATION forming part of Letters Patent No. 501,952, dated July 25, 1893, Application filed February 23, 1893. Serial No. l26S/1:59- (No modeli) To all whom it may concern:

Beit known that we, CLARK R. LONG and CHARLES H. KLINE, citizens of the United States, residing at Halsey, in the county of Linn and State of Oregon, have invented a new and useful Steam-Cooker, of which the following is a specification.

Our invention relates to improvements in steam-cookers; the objects in view being the production of a cooker which shall be vcapable of operating with a minimum amount of water and steam whereby but a small boiler or part for generating the steam is required; which shall utilize the same water over and over again by a subsequent condensation of the steam after it has ascended and circulated through the cooker, the said device be- Y the openings 3 in said water-chamber.

ing of cheap and simple construction and adapted to be conveniently operated.

With these and other objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawingsz--Figure 1 is a vertical longitudinal sectional vieWof asteamcooker constructed in accordance with our invention, the same being in position as when cooking. Fig. 2 is a detail in perspective of the removable frame for supporting the-cooking-trays. Fig. 3 is a detail in perspective of one of said trays.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practice we employ a water-chamber 1, the same being provided withla conical dome 2 whose base is secured direct to the bottom of said chamber and at its apex is provided with an escape-opening 3.

Rising from the outer edge of the waterchamber 1 is a series of short vert-ical standards 4 whose upper ends are slightly above Supported by and secured to the upper ends of the standards 4 is the cylindrical steam-chamber 5 which may be of other shape in crosssection if desired. The bottom of the steamchamber is provided with an opening which corresponds with the opening d in the waterchamber,so that communication is established between the water-chamber and the steamchamber.

Secured to and encircling the steam-chamber 5, a short distance below the upper end of the same, is a iiared, and in this instance annular, collar or ange 6 whose upper end extends beyond that of `the steam-chamber, and inasmuch as said collar or flange 6 is flared it combines with the wall of the steamchamber 5 to produce an intermediate annular-gutter 7. This annular gutter 7 is provided at one side with an opening 8, and vertically below the same an opening 9 is formed in the conical dome 2 of the water-chamber, the said openings 8 and 9 being connected by means of a return-pipe 10secured to the eX- terior of the steam-chamber 5.A

The steam-chamber is provided with an ordinary removable cover` 11, which when in position serves to close the upper end of the steam-chamber somewhat snugly, though of course it is not steam-tight, and hence while it retards the escape of steam said steam will in time as it passes up through the steamchamber wholly escape therefrom.

Within the flared liange or collar 6 there is seated a removable water-containing condensing-pan 12, the same being removable and being designed to receive cold water, the object of which will hereinafter appear.

In order to support the pans or trays hereinafter described and enable them to be placed within and removed from the steam-chamber as an entirety we lprovide a removable frame 13 adapted to be seated in said steam-chamber and to contain vthe pansfor trays whereby the entire series may be lifted for the purpose of placing them within the cooker or withdrawing them from the same after the food' has been cooked. This frame'- consists of a lower base-ring lepreferably formed of galvanized-wire, and crossing the base-ring at right angles to each otherand secured thereto is a pair of galvanized-wires 15 whose terminals beyond the base-ring are bent upward,

IOO

dimensions of the steam-chamber and pans or trays. Each pan or tray is ,provided with a removable cover 2O designed to tightly fit the same and the latter upon its upper side is provided With a series of lugs 2l so that the pan or tray thereabove Will not rest iiatly thereoubut will "be slightly/arranged thereabove producing an intermediates pace through which the steam may circulate.

whose operation We will now proceed to de scribe: The pans ortrays have placed'therein: the different articles to 'be cooked such as' meats, puddin gs, vegetables, dto., after which their covers are placed in position and they are vmounted one upon the'otherfinthe frame. The water-chamber 1 iisilled -vvithwater=and the frame lifted and lo-wered into ,position in` the:steam.chamber, after-Which l`the bails of the frame are turned down,1the coverjll placed inposition upon the steam-.chamber,1and the cold vvater pan ortray -12 seated .1in gposition in the collar or flange 6. The device being placed upon :a stovesteam is .generated :inthe l chamber :1 andascendsffrom thence into the steam-chamber 5 where Vit is caused to-circuzin'tostearn. -In this manner Ait will YbeseenA that the water isfutilized over and=overfagainv being first 'turned'into steamthen .condensed and returned ito the starting point `so that av minimum amount of Water will befsufcient -toloperate the device.

1Itwillfurthermore ybe rseen vthat tthe pecu- .liarvshapeV-given to the water-chamber 1, that is thelargearea lor bottom -surface,-ex,poses -to the-greatest advantage the water contained thereinto thefaction of the heat so thatsteam is quickly produced anda hot :fire 4to produce the-same is unnecessary. The-conical dome quickly brings the-steam to they center :or -es- Fcape-openingthereof whereby itis discharged in volume directly into the 4steam-chamber, andbyfreason of the pans or trays 19 being spaced apart allparts of the same are exposed fto vthe action of the steam.

rThe cover 11 serves to retain the Jsteam .i-n the steam chamber a sufficient lengthfof timeto extract all of its virtues, after :which it is permitted to escape and is immediately broughtinto contact with the coldsurface of fthelcold Watergpan by which -it is condensed,

falls back upon the cover 11, is gathered, and

returned Ato :the starting point.

When the edibles are cooked it is simply necessary to remove the cold water pan and cover 11 and by means of the bails lift the frame from the steam-chamber. No bad eftfect'kvvill result .from Elea-ving .the =edibles in the cooker longer than necessary, in thatthey v cannot become burned or injured, and there- Thiscompletestheconstruction of thecooker fore should one become cooked before the others it may remain until all are cooked.

Having described our invention, what we claim is 21. Inra-'steamscookeu the combination with a Water or boiler-chalnber having an opening in its top, a steam-chamber arranged thereover and communicating therewithandadapt- -ed to receive t,the 'cooking;pans,anfannular collarencircling the -upper end Iof .thefsteamchamber :and lcombining there-With :tolform an annulargutt-enand a return pipe leading from said gutter to the Water-chamber, of a series of removable trays-orpans arranged in the steam-chamber, Ia `cover for said `steamchamber, and a cold -fwater panor tray arranged-in thecollarabo-ve the steam-chamber,
